Difference Between Mountain Time and Eastern Time - GeeksforGeeks (2024)

The United States is divided into six standard time zones: Pacific, Mountain, Central, Eastern, Alaska, and Hawaii-Aleutian. The difference between Mountain Time and Eastern Time is one hour. Mountain Time is two hours behind Pacific Time and one hour ahead of Central Time, while Eastern Time zone is one hour ahead of Central Time and one hour behind Alaska Time.

This difference in time can cause confusion for those who travel or conduct business across time zones, as well as for those who live in areas that observe Daylight Saving Time.

Difference Between Mountain Time and Eastern Time

Mountain Time and Eastern Time are two of the four standard time zones used in the United States. The difference between the two is exactly two hours, with Mountain Time being two hours behind Eastern Time zone. Understanding the difference between these time zones can be important when scheduling events or making plans that involve people in different time zones.

What is Mountain Time?

Mountain Time (MT) is used in states such as Arizona, Colorado, Montana, New Mexico, Utah, and Wyoming. Eastern Time zone (ET) is used in states such as Connecticut, Delaware, Florida, Georgia, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, and West Virginia.

For example, when it is 12:00 PM Eastern Time, it is 10:00 AM Mountain Time. This means that if you are on a conference call scheduled for 12:00 PM ET, and you are located in Denver, Colorado (which is in the Mountain Time zone), you would need to dial in at 10:00 AM.

It’s also worth noting that certain states such as Idaho, Indiana, and Kentucky are split between the Mountain and Eastern Time zones. This can make it even more confusing for people who live in these states and travel frequently.

What is Eastern Time?

Eastern Time, also known as ET or EST, is the time zone that covers the states of Connecticut, Delaware, Florida (excluding the western panhandle), Georgia, Indiana (excluding the northwest corner), Kentucky (excluding the western half), Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Vermont, Virginia, and West Virginia.

The time in eastern time zone is five hours behind Coordinated Universal Time (UTC-5) during standard time and four hours behind (UTC-4) during Daylight Saving Time.

It’s important to note that the Navajo Nation in Arizona observes Mountain Standard Time year-round. Also, some states have areas which observe different time zones, such as the Florida panhandle which mostly observes Central Time. It’s always a good idea to double-check the time zone when planning travel or scheduling appointments across different regions.
